Closed circulatory system
Open circulatory system
Vertebrates have a closed circulatory system.
Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness.
Blood is pumped by a heart through vessels and does not normally fill body cavities.
The open circulatory system is common to mollusks and arthropods (invertebrates).
Open circulatory systems pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells.
Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
